ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine （TCM） constitution and factors associated with hyperuricemia （HUA） in the HUA population， providing a reference for persona-lized prevention and management of HUA. MethodsA cross-sectional study was conducted among individuals who had completed both serum uric acid （SUA） testing and TCM constitution identification during health examinations. According to SUA levels， participants were divided into a hyperuricemia group and a normal SUA group； according to the constitution identification results， participants were classified into balanced constitution， single biased constitution， and mixed constitution. The distribution characteristics of TCM constitution were compared between the two groups； participants in the hyperuricemia group were stratified by sex and age （≥18 years and ＜40 years， ≥40 years）， and the distribution characteristics of TCM constitution were compared across different sex and age groups. Logistic regression was used to analyze factors associated with HUA， with further stratified analyses by sex and age. ResultsA total of 10 920 participants were included， comprising 4170 cases （38.19%） in the hyperuricemia group and 6750 cases （61.81%） in the normal serum uric acid group. According to TCM constitution， there were 420 cases （3.85%） with balanced constitution， 6108 cases （55.93%） with single biased constitution， and 4392 cases （40.22%） with mixed constitution. In the hyperuricemia group， there were 80 cases （19.05%） with balanced constitution； 2275 cases （37.25%） with single biased constitution， among which damp-heat constitution （1205 cases， 52.97%）， phlegm-dampness constitution （500 cases， 21.98%）， and qi-stagnation constitution （181 cases， 7.96%） accounted for relatively high proportions； and 1815 cases （41.33%） with mixed constitution， among which mixed constitution involving phlegm-dampness （51.35%， 932 cases）， mixed constitution involving blood stasis （47.00%， 853 cases）， and mixed constitution involving damp-heat （41.21%， 748 cases） accounted for relatively high proportions. Logistic regression showed that qi-stagnation constitution （OR=1.68）， mixed constitution involving qi-stagnation （OR=1.53）， mixed constitution involving phlegm-dampness （OR=1.55）， and mixed constitution involving blood stasis （OR=1.50） were independently associated with HUA （P＜0.05）. Sex-stratified analysis showed that mixed constitution involving phlegm-dampness was positively associated with HUA risk in females； age-stratified analysis showed that， among individuals aged ≥18 and ＜40 years， qi-stagnation constitution， mixed constitution involving qi stagnation， and mixed constitution involving phlegm-dampness were positively associated with HUA risk （all P＜0.05）. ConclusionThe prevalence of HUA differs markedly by sex and age. Mixed constitution accounts for a higher proportion of HUA patients. Qi-stagnation constitution， mixed constitution involving qi stagnation， mixed constitution involving phlegm-dampness， and mixed constitution involving blood stasis are associated with HUA. Notably， the specific association of mixed constitution involving phlegm-dampness in females and qi-stagnation constitution in young adults is particularly prominent.

Objective To clarify the connotation of TCM doctors'work performance,explore the evaluation indicators system of TCM doctors'work performance conforming to the characteristics of TCM,and provide a basis for reasonable measurement of TCM doctors'work performance.Methods The connotation of TCM doctors'work performance was sorted out by literature data method,the TCM doctors'work performance evaluation index was constructed in line with the characteristics of TCM by grounded theory method,and 412 TCM doctors from 1 1 hospitals in Zhejiang Province were investigated by questionnaire method,and the scientificity of the evaluation index was tested by project analysis and reliability and validity analysis.Results The connotation of TCM doctors'work performance was clarified,and three first-level indicators,14 second-level indicators and 23 third-level indicators,including diagnosis and treatment workload,work quality and characteristics,teaching and scientific research,were established.Project analysis showed that all indicators had good discrimination and homogeneity,Cronbach's coefficient showed that the constructed indicators had high internal consistency,and the 3 common factors extracted by exploratory factor analysis were consistent with the preset first-level indicators.Conclusion It scientifically constructs the performance evaluation index of TCM doctors,which can provide reference for optimizing the setting of performance evaluation index of TCM doctors.

Objective To investigate the status quo of work performance appraisal,sense of salary fairness and salary satisfaction of traditional Chinese Medical(TCM)doctors,and to explore the effect of performance appraisal on salary satisfaction and the mediating effect ofsense of salary fairness between them.Methods A questionnaire survey was conducted among 412 TCM doctors selected from 1 1 public hospitals of different categories and grades in Zhejiang Province.Descriptive analysis,analysis of variance and structural equation model were used to analyze the data.Results The scores of Chinese Medicine characteristics(3.41),sense of salary fairness(3.15)and salary satisfaction(3.07)in the work performance appraisal of TCM doctors were between average(3)and better(4).The work performance appraisal of TCMdoctors had a positive effect on pay equity(β=0.714,P＜0.001),the sense of salary fairness of TCM doctors completely mediated(β=0.618,P＜0.001)the effect of TCM characteristics on salary satisfaction(β=0.084,P＞0.05).Conclusion It is suggested that the performance appraisal of TCM doctors should be improved and a fair and reasonable performance salary system should be established,and then enhance their salary satisfaction.

Objective To evaluate the diagnostic value of dual-layer spectral CT(DLCT)virtual non-contrast(VNC)imaging combined with iodine maps in differentiating early post-endovascular therapy(EVT)intracranial hemorrhage from contrast extravasation.Methods Retrospective analysis of 97 patients who underwent DLCT immediately after EVT was conducted.Taking 24-hour follow-up CT/MRI as the gold standard,patients were divided into hemorrhage and non-hemorrhage groups,and their clinical data were compared.VNC CT values and iodine concentration(IC)were measured.Spearman's rank correlation was used to analyze the relationship between VNC CT and IC values,and ROC curve analysis using R software to evaluate the diagnostic performance of VNC,iodine maps,and their combination.Results Among 97 patients,51(52.6%)showed no intracranial hyperdense lesions,while 46(47.4%)with abnormal densities were analyzed.Using 24-hour postoperative CT/MRI as reference stan-dard,among the 46 patients ultimately included in the analysis,38 cases(82.6%)were non-hemorrhagic and 8 cases(17.4%)hemorrhagic.No significant differences existed in age,sex,or treatment methods(all P>0.05).VNC CT values and IC showed significantly negative correlation(r=-0.537,P<0.01).ROC analysis revealed AUCs of 0.917(95%CI:0.786～0.999)for VNC,0.878(95%CI:0.719～0.999)for IC,and 0.919(95%CI:0.812～0.999)for the combination of the two(P<0.05 for combined vs.individual methods).Optimal thresholds were 53.6 HU for VNC and 0.605 mg/ml for IC.Based on the final analysis of 46 enrolled patients,the sensitivity of VNC,iodine map,and their combination in differentiating early cerebral hemorrhage from contrast extravasation was 88.9%,94.3%,and 91.4%,respectively;the specificity 94.3%,77.8%,and 88.9%,respectively;and the accuracy 90.9%,90.9%,and 93.2%,respectively.Conclusion The DLCT VNC-iodine map combination significantly im-proves differentiation between post-EVT hemorrhage and contrast extravasation,and it is recommended for routine clinical application.

Given the increasing concern regarding antibacterial resistance, the antimicrobial properties of naphthoquinones have recently attracted significant attention. While 1,4-naphthoquinone and its derivatives have been extensively studied, the antibacterial properties of 5,8-dihydroxy-1,4-naphthoquinone derivatives remain relatively unexplored. This study presents a comprehensive in vitro and in vivo analysis of the antibacterial activity of 35 naturally sourced and chemically synthesized derivatives of 5,8-dihydroxy-1,4-naphthoquinone. Kirby-Bauer antibiotic testing identified three compounds with activity against methicillin-resistant Staphylococcus aureus (MRSA), with one compound (PNP-02) demonstrating activity comparable to vancomycin in minimum inhibitory concentration, minimum bactericidal concentration (MBC), and time-kill assays. Microscopic and biochemical analyses revealed that PNP-02 adversely affects the cell wall and cell membrane of MRSA. Mechanistic investigations, including proteomic sequencing analyses, Western blotting, and RT-qPCR assays, indicated that PNP-02 compromises cell membrane integrity by inhibiting arginine biosynthesis and pyrimidine metabolism pathways, thereby increasing membrane permeability and inducing bacterial death. In an in vivo mouse model of skin wound healing, PNP-02 exhibited antibacterial efficacy similar to vancomycin. The compound demonstrated low toxicity to cultured human cells and in hemolysis assays and remained stable during serum incubation. These findings suggest that PNP-02 possesses promising bioactivity against MRSA and represents a potential novel antibacterial agent.

Objective:To investigate whether repeated tirofiban injections can continuously inhibit platelet aggregation in the arterial duct and affect its closure in neonatal canines.Methods:Four 24-month-old pregnant beagles underwent cesarean sections in two batches (two dogs per batch) 1-2 days before the expected delivery date at the Xuzhou Medical University Animal Experiment Center. The first litter of 21 neonates served as the control group (receiving 10 ml/kg normal saline) and were randomly divided into 1-h ( n=7, injected immediately after birth), 4-h ( n=7, injected at 0 h and 2 h after birth), and 12-h subgroups ( n=7, injected at 0 h, 2 h, 4 h, 6 h, 8 h, and 10 h after birth). The second litter of 18 neonates served as the experimental group (receiving 10 ml/kg tirofiban) with identical subgroup assignments ( n=6 per subgroup). Echocardiography was performed at 1 h, 4 h, and 12 h after birth to measure arterial duct inner diameter, maximum shunt velocity, and left atrial diameter/aortic root diameter (LA/Ao) ratio. Plasma platelet-derived growth factor (PDGF) was detected by enzyme-linked immunosorbent assay, while platelet membrane glycoprotein Ⅱb-Ⅲa in the arterial duct was assessed by Western blot and immunohistochemistry. Data were analyzed using t-tests, one-way ANOVA, Chi square tests, or Fisher's exact test. Results:No significant bleeding tendency occurred in either group. Two control neonates (one each in the 4-h and 12-h subgroups) died. In both control and experimental 1-h subgroups, all arterial ducts remained open, with no significant differences in ductal diameter, shunt velocity, or LA/Ao between groups (all P>0.05). In the 4-h subgroups, all experimental neonates had patent ducts arteriosus, while two controls exhibited closure; the experimental group had larger ductal diameters [(1.05±0.05) vs. (0.55±0.44) mm, t=－2.75, P<0.05)] and higher LA/Ao ratios (1.31±0.09 vs. 1.14±0.03, t=－4.90, P<0.05), but lower maximum shunt velocities [(107.06±17.47) vs. (153.74±12.78) cm/s, t=4.54, P=0.002). In the 12-h subgroups, all the controls had closed arterial ducts, while four of six experimental neonates exhibited closure, though the difference in closure rate was not statistically significant (6/6 vs. 4/6, Fisher's exact test, P=0.455). Plasma PDGF and glycoprotein Ⅱb-Ⅲa levels did not differ between two 1-h subgroups (all P>0.05). However, the 4-h and 12-h experimental subgroups showed lower PDGF levels [(373.5±13.1) vs. (880.3±80.2) pg/ml, t=10.81; (356.7±35.0) vs. (1 111.2±125.3) pg/ml, t=9.74; both P<0.05] and reduced glycoprotein Ⅱb-Ⅲa expression (0.32±0.07 vs. 0.80±0.23, t=3.29; 0.42±0.07 vs. 0.92±0.26, t=3.24; both P<0.05) compared to controls. Conclusion:Repeated tirofiban injections sustainably inhibit platelet aggregation in the arterial duct of neonatal canines and delay ductal closure, suggesting that intraductal platelet aggregation may be one factor influencing this process.

Laparoscopic common bile duct exploration(LCBDE), as a safe and feasible surgical procedure for the treatment of choledocholithiasis, has been widely applied in clinical practice.However, due to the generally declined organ function, comorbidities, and polypharmacy associated with elderly patients, there is currently no unified consensus on the application of LCBDE in elderly patients with choledocholithiasis.This review aims to summarize the current status of LCBDE for the treatment of choledocholithiasis in the elderly patients, in order to provide reference for clinicians to select appropriate treatment strategies.
